Description
Die Erfindung betrifft eine Befestigung von Kunststoffteilen am Chassis eines Kraftfahrzeugs, wobei am Chassis ein Führungselement befestigt ist, auf dem das Kunststoffteil in der Symmetrieachse des Führungselements beweglich gelagert ist und das Kunststoffteil über Dämpfungs- bzw. Federelemente gelagert ist.The invention relates to a fastening of plastic parts to the chassis Motor vehicle, wherein a guide element is attached to the chassis on which the plastic part is movably mounted in the axis of symmetry of the guide element is and the plastic part is mounted on damping or spring elements is.
Bei der Befestigung von Kunststoffteilen, wie Motorhauben oder Kotflügel am Chassis eines Kraftfahrzeugs, ist auf absolute Bündigkeit zu achten. Durch Wärmeausdehnung der Kunststoffteile entstehen leicht ungerade Fugen, die sehr häßlich wirken.When attaching plastic parts such as hoods or fenders to Chassis of a motor vehicle, attention must be paid to absolute flushness. By Thermal expansion of the plastic parts creates slightly odd joints that look very ugly.
Aus der gattungsgemäßen DE 531 454 C ist eine Befestigung von Kunststoffteilen am Chassis eines Kraftfahrzeugs bekannt, wobei am Chassis ein Führungselement befestigt ist, auf dem das Kunststoffteil in der Symmetrieachse des Führungselements beweglich gelagert ist und das Kunststoffteil über Dämpfungs-bzw. Federelemente gelagert ist.From the generic DE 531 454 C is a fastening of plastic parts known on the chassis of a motor vehicle, with a guide element on the chassis is attached, on which the plastic part in the axis of symmetry of the guide element is movably mounted and the plastic part via damping or. Spring elements is stored.
Aus dem DE 71 07 748 U ist ein Halter für Innenauskleidungen in Räumen von Land-, Wasser- oder Luftfahrzeugen oder Erschütterungen ausgesetzten Gebäuden, insbesondere zum Halten von Vorsatzplatten für Wände oder Fußböden, bekannt. Der Halter besteht aus einem an der Wand, Decke oder Fußboden befestigten Gummikörper an dem die Vorsatzplatten befestigt sind.From DE 71 07 748 U is a holder for interior linings in rooms from Buildings exposed to land, water or air vehicles or vibrations, especially for holding facing plates for walls or floors, known. The holder consists of one on the wall, ceiling or floor attached rubber body to which the attachment plates are attached.
Der Erfindung liegt die Aufgabe zugrunde, eine Befestigung von Kunststoffteilen am Chassis eines Kraftfahrzeugs gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, die Wärmeausdehnungen der Kunststoffteile ausgleicht. The invention has for its object a fastening of plastic parts to the chassis of a motor vehicle according to the preamble of claim 1 create, the thermal expansion of the plastic parts compensates.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß es sich bei den Kunststoffteilen um sichtbare Außenhautteile eines Kraftfahrzeugs handelt und das Dämpfungs- bzw. Federelement im Querschnitt wellenförmig geformt ist.According to the invention, this object is achieved in that the Plastic parts are visible outer skin parts of a motor vehicle and the damping or spring element is wavy in cross section.
Die bewegliche Lagerung über ein Dämpfungs- bzw. Federelement gleicht Wärmeausdehnungen der Kunststoffteile aus, so daß keine häßlichen ungeraden Flächen entstehen.The movable bearing via a damping or spring element is the same Thermal expansion of the plastic parts, so that no ugly odd Areas are created.
Vorteilhafterweise umgreift das Kunststoffteil das Führungsteil und ist auf diesem rutschend gelagert. Durch das Umgreifen ergibt sich automatisch eine Führung und eine Beweglichkeit nur in Achsialrichtung des Führungsteils.The plastic part advantageously engages around and is on the guide part slidably mounted. A change of grip automatically results in guidance and mobility only in the axial direction of the guide part.
In bevorzugter Ausführungsform ist das Führungselement im Querschnitt U-förmig geformt und bildet somit eine Art Zapfen.In a preferred embodiment, the guide element is in cross section U-shaped and thus forms a kind of pin.
Das Dämpfungs- bzw. Federelement ist in einer bevorzugten Ausführungsform einerseits am Kunststoffteil und andererseits am Führungselement befestigt.The damping or spring element is in a preferred embodiment fixed on the one hand to the plastic part and on the other hand to the guide element.
Erfindungsgemäß ist das Dämpfungs- bzw. Federelement im Querschnitt wellenförmig geformt. Durch den Winkel und die Bogenweite läßt sich die Dämpfungskennlinie des Dämpfungselements festlegen.According to the invention, the damping or spring element is wavy in cross section shaped. The damping characteristic can be determined by the angle and the arc width of the damping element.

Figur 1 zeigt mit dem Bezugszeichen 2 eine Zugstrebe als Chassis eines Kraftfahrzeugs.
An diesem Chassis 2 ist ein Kunststoffteil 1 über die erfindungsgemäße
Befestigung festgelegt. Das Kunststoffteil 1 ist hier nur im Ausschnitt gezeigt
und ist ein Frontmittelteil einer Motorhaube.Figure 1 shows the reference numeral 2 a tension strut as the chassis of a motor vehicle.
On this
Zur Befestigung ist am Chassis 2 ein Führungselement 3 mittels Schrauben 7
angeschraubt, welches einen U-förmigen Querschnitt aufweist. Es bildet somit
eine Art Zapfen. Im Kunststoffteil 1 ist eine entsprechende Öffnung angeordnet,
durch die das Führungselement 3 ragt. Das Kunststoffteil 1 umgreift demnach
das Führungselement 3 und ist daher in einer Achse, nämlich in der Längsachse
des Führungselements 3 beweglich gelagert. Es kann auch vorteilhaft sein, das
Führungselement konisch auszubilden. Die das Führungselement 3 umgreifende
Öffnung ist an Ihrem Rand umgebogen, so daß sich eine größere Auflagefläche
ergibt. A guide element 3 is attached to the
Ferner ist am Kunststoffteil 1 ein Dämpfungs- bzw. Federelement 4 befestigt, z.B.
geklebt. Dieses Dämpfungs- bzw. Federelement 4 ist wellenförmig geformt und mit
der Stirnseite des Führungselements 3 über eine Schraube 5 verschraubt. Beidseits
der Schraube 5 ist jeweils ein Bogen 6 angeordnet. Über den Winkel und die
Bogenweite läßt sich die Dämpfungskennlinie festlegen.Furthermore, a damping or spring element 4 is attached to the plastic part 1, e.g.
glued. This damping or spring element 4 is wave-shaped and with
the end face of the guide element 3 screwed via a
Figur 2 zeigt eine alternative Ausführungsform mit einem Chassis 2 an dem ein
Führungselement 3 angeschweißt ist. Das Kunststoffteil 1 ist in seinem das
Führungselement 3 umgreifenden Teil als Dämpfungs- bzw. Federelement 4
ausgebildet. Beiderseits des Führungselements 3 ist das Dämpfungs- bzw.
Federelement 4 sinusförmig geformt, so daß sich über das Führungselement 3 eine
Führung in der Längsachse des Führungselements 3 ergibt und über das
Dämpfungs- bzw. Federelement 4 eine Dämpfung erreicht ist. Über die Ausbildung
des Winkels und der Bogenweite läßt sich wieder die Dämpfungskennlinie festlegen. Figure 2 shows an alternative embodiment with a
